Abstract

Phytochemical, to xicity and antibacterial act ivity tests of total extract, fractions of n-heksana, ethyl acetate and ethanol-water fro m mahang leaf (Macaranga pruinosa (M.) M. A.) fro m KRUS (Kebun Raya Unmul Samarinda), East Kalimantan has been carried out. Based on the secondary metabolites phytochemical test of the (Macaranga pruinosa (M.) M. A.) leaf show that total extract is contain alkaloid and steroid. n-hexane fraction is contain alkaloid and steroid. Ethyl acetate fract ion is contain steroid. Ethanol-water fract ion is contain alkaloid and phenolic. Brine shrimp lethality test values obtained Lethal Concentration 50 % (LC 50 ) total extract 27,5036 ppm , n-heksana fraction 12,0773 pp m, ethyl acetate fraction 23719,2305 ppm and ethanol-water fraction 250,0384 ppm. Antibacteria act ivity test of extracts for Staphylococcus aureus bacteria (positive Gram) and Escherichia coli (negative Gram) minimum inhibitor consentration of 0-1 % (b/v) fro m ext ract fractions of n-heksana and fractions ethyl acetate for Staphylococcus aureus bacteria and fractions ethyl acetate for Escherichia coli bacteria.

Abstract

The purpose of this research was to determine the quality of fat in the abdomen djambal patin fish, which includes parameters water content, free fatty acid, iodine number, peroxide number, and the physical characteristics of the fat which includes the melting and freezing. Each parameter in each sample were given treatment three replications. The method used to determine water content, free fatty acid, iodine number, peroxide number is method Open oven, alkalimetri titration and iodometric titration.The results for water content, free fatty acid, peroxide number and iodine number in each sample from the average of three repetitions was 4.4%, 0.0563%, 11.52 meq and 8.34. Based on these results it can be concluded that the water content and the peroxide number weren’t conform in Indonesian national standards, while the free fatty acid content and iodine number were conform in Indonesian national standards.
